  1. WHMIS Workplace Hazardous Materials Information System

  2. “Right to Know” Worker’s have access to information through their employer.

  3. Purpose of WHMIS • Provides Information on Hazardous Materials used in Workplace • Facilitates the Process of Hazard Identification • Ensures Consistency of Information in all Canadian Workplaces

  4. Legislation Federal • Bill C-70 • Part of the Canada Labour Coded Provincial – Bill 79 • Ontario Reg. 644/88 • Occupational Health & Safety Act • Policed by Ministry of Labour

  5. Exemptions From WHMIS • Explosives • Drugs • Pesticides • Radioactive Materials • Hazardous Wastes • Products being transported – T.D.G. Act • Consumer Products/Tobacco/Manufactured Articles

  6. Three Components of WHMIS • Labels • Supplier Label • Workplace Label • Material Safety Data Sheets (MSDS) • Worker Education

  7. Duties of the Supplier • Classify Product • Apply Supplier Label • Provide Material Safety Data Sheet • Update MSDS’s at least every 3 years

  8. Duties of the Employer • Conduct Workplace Inventory • Ensure Proper Labeling is Used • Label Piping Systems/Vessels/Reactors • Maintain and Make Available MSDS’s • Train Workers

  9. Duties of a Worker • Report missing or damaged labels or MSDS’s • Participate in Training • Apply Knowledge and Training

  10. WHMIS Hazard Classifications

  11. Class A • Compressed Gas • Any Hazardous Material that is contained under pressure including compressed gas, dissolved gas, or liquefied gas

  12. Compressed Gas Cylinders • store and transport with safety cap • comply with storage restrictions • DO NOT store fuel gas with oxygen • secure in an upright position • use in a well ventilated area

  13. Class B • Flammable and Combustible Material • Flammable Gases • Flammable and Combustible Liquids • Flammable Solids • Flammable Aerosols • Reactive Flammable Material • Methanol, Toluene, Butane, Acetone

  14. Flammable Materials • Store liquids in Flammable Storage Cabinet • Explosion-proof fixtures required • NEVER store with oxidizers • Keep away from heat, ignition sources, and direct sunlight • Use static lines when transferring

  15. Class C • Oxidizing Material • Any Hazardous Material which causes or contributes to the combustion of another material by giving oxygen or some other oxidizing substance, whether or not it is combustible. • Organic Peroxides • Chlorates, Nitric Acid, Peroxides, Permanganates, Perchlorates, Nitrites, Nitrates

  16. Oxidizers • Easily oxidize metal powders, organic materials • Segregate from other materials, such as organic solvents • PPE and/or explosion barriers may be required

  17. Class D1 • Poisonous & Infectious Materials • Material causing immediate and serious toxic effects • Materials which are potentially fatal or may cause permanent damage if inhaled, swallowed, or absorbed through the skin, or may burn the skin or eyes upon contact

  18. Class D2 • Poisonous & Infectious Materials • Material causing other chronic or long term effects • Material which may • cause death or permanent damage as a result of repeated exposure over an extended period of time; • may be an irritant to the skin, eyes, or respiratory system; • may cause cancer, birth defects, or sterility.

  19. Class D3 • Poisonous & Infectious Materials • Biohazardous and Infectious Materials • Materials which may cause disease in humans and animals, such as viruses, bacteria, and fungi; may also include cultures and diagnostic specimens such as blood, urine, and body tissue.

  20. Class E • Corrosive Material • Material which may corrode aluminum and steel or human flesh • Material which are anhydrous corrosive gases

  21. Inorganic Acids • Sulfuric Acid, Nitric Acid, Perchloric Acid, Hydrochloric Acid • Segregate from bases and organic compounds • Store in a ventilated acid cabinet • Know the location of eye washes and safety showers • Store on lower shelves

  22. Bases • Sodium hydroxide, ammonium hydroxide • Segregate from acids and organic compounds • Store in a ventilated cabinet • Know the location of eye washes and safety showers • Store on lower shelves

  23. Class F • Dangerously Reactive Material • Materials which undergo vigorous polymerization, decomposition, or condensation • Materials which become self-reactive under conditions of shock, or increased temperature or pressure • Materials which react vigorously with water to produce a very toxic gas

  24. WHMIS Labels

  25. Supplier Label • Product Identifier • Hazard Symbols • Border • Bilingual • Risk Phrases and Precautions • First Aid • Safe Handling Precautions • Reference to MSDS • Supplier Information

  26. Workplace Label • Product Identifier • Safe Handling Precautions • Reference to MSDS

  27. Workplace Label Uses • Transfer of material from a Supplier Labelled container to another container • Replacement of a damaged Supplier Label

  28. Hazardous Ingredients Preparation Information Fire & Explosion Hazard Toxicological Properties First Aid Measures Product Information Physical Data Reactivity Data Preventative Measures MSDS Contents
